 ## Next release
 
+### Upcoming Breaking Changes
+- Receipt compaction will be enabled by default in a future version of Besu. After this change it will not be possible to downgrade to the previous Besu version.
+- --Xbonsai-limit-trie-logs-enabled is deprecated, use --bonsai-limit-trie-logs-enabled instead
+- --Xbonsai-trie-logs-pruning-window-size is deprecated, use --bonsai-trie-logs-pruning-window-size instead
+- `besu storage x-trie-log` subcommand is deprecated, use `besu storage trie-log` instead

 ### Breaking Changes
 - Remove deprecated sync modes (X_SNAP and X_CHECKPOINT). Use SNAP and CHECKPOINT instead [#7309](https://github.com/hyperledger/besu/pull/7309)
 - Remove PKI-backed QBFT (deprecated in 24.5.1) Other forms of QBFT remain unchanged. [#7293](https://github.com/hyperledger/besu/pull/7293)
